With the FBD language, engineers can build control logic by selecting and connecting function blocks, creating a cohesive and efficient control sequence. Aug 6, 2007 · One other advantage of FB over FC (from STEP7 programming perspective) is passing the parameters in/out to the function. me. I have done the same obesrvations regaurding the POU's(as u have said above) a) FB: Thus, we see the principle difference between functions and function blocks is the fact that internal memory allows function blocks to return different outputs despite repetition of the same input. The configuration and parameter settings for the drives is realized as follows 1. 0 PLC-Simulation software SIMATIC Control Function Library V1. k. program complex code in an SCL Block and interlocking section of Outputs in an FBD Block. See full list on instrumentationblog. But the difference is, you don’t call them, the operating system of the PLC calls these organization blocks, whether the operating system calls the OB cyclically as OB1 or whether it gets called when a certain event occurs, either way, the operating system takes care of it. We have written the data 1123, 7893, 12. I am currently using TIA V15 to program CPU315-2 PN/DP PLC. The next two function blocks are also build using the basic blocks. Project library – Integrated in the project and managed using the project – Allows the reusability within the project 2. We have 3 different options for a data instance of a function block, these options are: Single Instance. This function block can be taken from the library “DriveLib”, which can be opened in TIA Portal.
